Print, A History of Medicine in Pictures – ca. 1961 What is going on here? This poor kid does not look very happy! And understandably so. Titled “Jenner: Smallpox is Stemmed,” this print illustrates English physician Edward Jenner performing the first vaccination against smallpox in 1796. Jenner was able to prove that his discovery of vaccination… Continue reading
On Sunday August 21, members of the NHL’s Technical Team were at the Saint Louis Science Center to discuss the evolution of technology used by players, coaches and referees to make in-game decisions. These experts showcased some of the technology used right here in St. Louis’ Enterprise Center during St. Louis Blues games. Guests had… Continue reading
When we talk with our younger guests about hydroponics, we like to start off with a seemingly simple question: what does a plant need to grow? It seems like such an easy question to answer, but the more you start thinking about the answers, the more complex the question becomes. Somebody once asked the question… Continue reading
Hello again everyone! For those of you who don’t know me, my name is Chris, and I’m a new part-time facilitator at GROW this summer. Some of you might remember me from last year’s greenhouse blog posts, where I talked about everything from aphids, to fish, to commercial lettuce. Being a YES Teen with the… Continue reading
“Electricity is Life” by Midland Manufacturing was one of the best-selling, coin-operated electric shock machines in the early 20th century. Produced from 1899 to 1909, it was advertised as both a strength tester and electrical therapy device. For only a penny, patrons would receive a “healthy” electrical shock to treat a variety of potential ailments.… Continue reading
We have new toys in the bee yard! We recently installed broodminder scales under the GROW honeybee hives to help keep track of how they are doing without having to open the actual hives, which is especially challenging during winter. The scales take a lot of the guesswork out of beekeeping. Before, we could tell… Continue reading
Over the summer, we had an optimistic “aha moment” after visiting the VAST Produce hydroponics operation. Our intern, Christopher, and educator Andy returned from their field trip reporting that the folks at VAST seemed to use simple and affordable peat pellets for growing media in their deep water culture bed. If peat pellets could work… Continue reading
Welcome to the final GROW blog post written by me, Christopher. It’s been an awesome summer being a Youth Exploring Science teen working with the GROW team, and I’ve learned so much throughout this whole experience. But before the final goodbye, there’s a lot to recap about what happened this summer with the greenhouse. It… Continue reading
When we think of animals and ecosystems, we often think of vast savannas, rushing rivers or lush jungles. For many people, the ecosystem is a giant place where multitudes of plants, animals and other organisms live. But sometimes, an ecosystem can be very small, with much of the action taking place on just a few… Continue reading
During our visit with the brothers at VAST Produce, our tour guide, John, told us something very interesting about how he saw hydroponics and aquaponics advancing in the future. He said it was a “chicken and the egg situation” because he believed that to find major technological breakthroughs that would open the industry to more… Continue reading
